BRAKE-HEAD.

Specification of Letters Patent.

?atented Nov. 281, 1912.

To all whom it may concern:

Be it known that I, FREDERICK Conn- WALL, a citizen of the United States, residing at St. Louis, Missouri, have invented a certain new and useful Improvement in Brake- Heads, of which the following is a full,

nection with trnssed or solid brake beams,

the object being to provide the head with a removable wall which will permit the beam tobe'unhung without detaching the head from the brake hanger, or by connecting the movable wall to the brake hanger to permit the head and beam to be removed for purposes of renewal or repair.

An important feature of my invention resides in the fact that the beam can be unhung or the head removed without requiring any considerable play of the parts except in a vertical direction, and in inside hung beams, where there is comparatively little space for the brake beam and heads, this is a desirable feature.

In the drawings 1 indicates the brake head of any ordinary or approved construction, the rear wall of the socket of which is preferably provided with a seat for the head of a bolt 2.

3 is the sleeve on which the head is mounted, said sleeve having a circumferential groove provided with serrations in its bottom as is frequently employed with adjustable brake heads. While I have illustrated this form of sleeve which is usually identitied with trussed beams, it is obvious that serrated to cooperate with the serrations of the sleeve. The front end of this removable wall 4; is provided with a projection :8 which is received in a seat in the brake head to cooperate with a curved bearing lip which acts as a fulcrum. The outer end of the removable wall is provided with an opening through which the bolt 52 passes, a nut being threaded on said bolt to impinge against the removable wall and hold the same in positio-n. While I have shown this bottom wall as entirely remmnblc. it is obvious that it could be pivoted to the brake head so that it would swing down to permit the beam to drop.

In operation, if it is desired to unhang the beam, the nut is removed from'the bolt and the bottom wall taken out which will permit the brake beam to drop vertically through the opening thus provided. The parts of course may be reassembled by lifting the brake beam into position and replacing the removable wall and securing it in position.

In Fig. 3 I have shown a modified form in which the wall arranged at the top and provided with perforated lugs 4 for the attachment of the brake hanger. By this construction, the head may be removed with the beam and when the beam is unhung, the head is in readiness to be separated therefrom without requiring the removal of any fastening devices between the head and beam.

.Yhat I claim is;

1. A brake head provided with means whereby it may be adjustably secured to a brake beam and having an opening in one wall of its socket of such size as to permit the introduction and removal of the brake beam therethrough in a vertical direction, and means for securing the head on the beam in adjusted position.

2. A brake head adapted to be adjustably mounted on a brake beam and having an opening through one of its socket walls of such size and in such position as to permit the removal of the brake beam therethrough in a direction longitudinally of the head while a portion of the head remains con nected to the hanger.

A brake head provided with means for adjustably securing it on a brake beam and having :in-opening through its socket wall, which opening opens in a direction longitudinally of the head, and is of size to permit the removal of the brake beam therethrough,

and a movable membe: pivoted on the head spanning 'said opening to 'hold the brake beam in position in the head.

4. The combination of a brake beam, a brake head adjustably mounted thereon and means carried by said brake head for holding the same in adjusted position on the beam, said means also constituting connection with the brake hanger whereby, upon the removal of said means, the brake beam is unhung and the brake head disconnected from the beam.

5. The combination of a brake head having an opening through its socket wall through which the beam may be inserted and removed, a removable wall pivotally connected to said head at one end and provided with removable fastening devices at its other end, a sleeve having a circumferential groove on which the head is mounted, and a projection on said removable wall extending into the groove of said sleeve.

6. A brake head having a removable Wall permittin the removal of the beam longitudinally of the head, said wall being provided with a curved lip at one end. for engagement with the brake head, one face of said wall being curved to cooperate with the part of the brake beam on which the head is mounted, a projection extending from said curved face, and a perforated lug extending from the opposite end of said wall for cooperating with a fastening device. I

7. An adjustable brake head made in parts and having an opening in its socket wall so arranged to permit the removal of the brake beam therefrom in a vertical line, while one of said parts remains connected to the hanger. I
